GhostBed is yet another one of the latest direct-to-consumer, mattresses-in-a-box to hit the market. I was skeptical about this one at first until I realized that it is made by Nature’s Sleep, which is a respectable company that’s been around for 15 years. This was not just another marketing company trying to get in on the new mattress-in-a-box fad; it is an established mattress company taking advantage of the new distribution model.
